Hi @mauriziopinotti ,

We are currently exploring the possibility of updating the device_info_plus package to the latest version in the syncfusion_flutter_pdfviewer package. To proceed, we need to ensure compliance with our licensing requirements and conduct thorough testing of the syncfusion_flutter_pdfviewer package with the new version (13.0.0).
In the meantime, we kindly request that you use version 12.1.0 of the device_info_plus package when working with the syncfusion_flutter_pdfviewer package.

Regards,
Abinaya E
